Step-by-step explanation:
Because 6^2=6*6=36.
Answer:
3.14
Step-by-step explanation:
Given that:
Mean weight (m) = 79 ounces
Population standard deviation (s) = 13.1
Sample size = 47
Maximal margin of error associated with 90% confidence interval.
The margin of error is given by:
Zcritical * (standard deviation / sqrt(sample size)
Z critical at 90% confidence interval = 1.645
Hence,
Zcritical * (standard deviation / sqrt(sample size)
1.645 * 13.1 / sqrt(47)
1.645 * (13.1 / 6.8556546)
1.645 * 1.9108313
Hence, the margin of error is :
3.1433174885
= 3.14
4/9, is your answer.
Both numerator and denominator can go into 5.
20 divided by 5 is 4, 45 divide by 5 is 9.
Question 1 answer: 5/3 miles per hour
reason: 1/3 divided by 1/5
